Stage at presentation and survival of white and black patients with prostate carcinoma

Black men are known to have a higher incidence and mortality from prostate carcinoma than white men and are more likely to have a more advanced stage or grade of disease diagnosed.

In a Veterans Administration Medical Center where black and white men have the same eligibility for medical care, the authors reviewed the stage at presentation of 861 consecutive cases of prostate carcinoma diagnosed from 1969-1990. In addition, survival, stratified by race, stage, and grade, was determined on all men in whom prostate cancer was diagnosed from 1969-1985 (525 patients).

It was found that 26% of white and 52% of black men with prostate carcinoma presented with Stage D disease. Similar proportions of white and black men with prostate carcinoma presented with Stage D disease between 1969-73 as between 1986-90. The overall survival was poorer for black men because of their higher proportion of Stage D disease, but stratified for grade and stage, survival was similar in both races.

This study suggests that factors other than eligibility for medical care may be responsible for the higher proportion of black men with prostate carcinoma presenting with Stage D prostate carcinoma.
